function f=iunsdgt(c,g,a,varargin)
%IUNSDGT Inverse uniform non-stationary discrete Gabor transform
% Usage: f=iunsdgt(c,g,a,Ls);
%
% Input parameters:
% c : Cell array of coefficients.
% g : Cell array of window functions.
% a : Vector of time positions of windows.
% Ls : Length of input signal.
% Output parameters:
% f : Signal.
%
% IUNSDGT(c,g,a,Ls) computes the non-stationary Gabor expansion of the
% input coefficients c.
%
% IUNSDGT is used to invert the function NSDGT. Read the help of NSDGT
% for details of variables format and usage.
%
% For perfect reconstruction, the windows used must be dual windows of
% the ones used to generate the coefficients. The windows can be
% generated unsing NSGABDUAL.
